To assist in the explanation of'our invenc *c provided the accompanying ngs, in which a sido clovation of our machine, is a plum. vicw of the-same.

o .i on a somewhat enlarged sonic, a portion of th winding mechanism; and Fig. shows, on r. sir lor scilc, certain circular sows or cuticrs which compose the slitting mechanism of our machine.

While a machine of this class is desirable for use in kinds of in-(ucrini it is especially useful in slitting up lingo rolls of paper and throughout tho rcnniiinlcr of this specification we have described our. machine so used; but we do rot Wish to be understood as confining our nnnrlu'nc to this use exclusively.

liel'c l in;; to rho drawings the letters a and (1" donoto the side frames of our inachins and c tho main or driving shaft suitillustii,

ably journclcd in said frames and at right angles thereto. a driving pulley d and on its opposite end a pulley 6 whose face is of considerable width for purpose hereinafter explained.

Located approximately over the main shaft and parallel thereto arctvvo shafts '.f

men? with each other and are suitably supported near each end in bearings provided in upwardly extending portions ofthe frames (2, and Z2. Shafts f'and g serve as axial supports for circular cutters or saws h which arc adjustahly located on said shafts and form the slitting mechanism-of our machine. Shafts f and g are caused to rotate in unison by meansof meshing spur gears h located on the ends of the sanro, respectively, and approximately over the pulley d. opposite gear a pulicy k which lat; tor is driven from pulley ed by means of a belt in.

be readily understood that when main shaft 0 is set in revolution, motion therefrom will be imparted bynzeans of its pulley e conncction with rolls of diilcrent' Shaft f when in motion will, through spur gears h on said shaft and the companion shaft g import. in turn motion to said shaft g. thereby causing the shafts f and g to'rovolve in unison.

The circular cutters or sows, mounted upon shafts f and g, as already dcscribcd, are denoted by rcfercnce letter n and are prcferably formed of suitable sheet inoial. cutters on shaft f are so located that their g to prod uco n shes-ring cut and the cutters on each shaft are located a distance apart equal to the width of strip it is desired to out, the cutters serving when revolving, as shown by the Arrows of Fig. 1, to slit up a web of paper fed bctvccu the some into strips Whose width is regulated by the distance apart at which said cutters are adjusted.

Frames a and b are each provided at one end (the left hand as shown in the drawings) With journal bearings o for the reund g. 'lhesc shafts are in vertical aligm,

loo

Shaft f bears upon its end From the description thus for given it will circumferential edges overlap those of shaft Said shaft bears'upon one end through belt m to pulley is on shaft f.

The

ception of a spindle b' which latter serves as an axial support for the roll of paper being operated upon. Fromthe rolliof paper thus supported the web is drawmforward to the slitting mechanism, already described, after which operation the several strips pass on to be rewound or reeled into individual rolls, which rewinding mechanism We will now proceed to describe.

Near the right hand end of our machine, supported in suitable bearings, is located a spindle 1) having upon one end a pulley 11' connected by belt s to the pulley c already referred to, the face of pulley c being sufficiently wide to receive both the belt 712" and also the belt 5. Belt 5 is normally so slack that no motion would be imparted thereby from pulley a to the pulley p but to take up such slack, when it is desired to set in revolution shaft p, we have provided a belt tightener consisting; of an ordinary foot lover a pivotally supported near the lloor toward the right hand end of the machine. Foot lever u. carries an idle pulley u' to engage the belt 3 when the same is to be tightened. When foot lever 11" is rocked downward as shown in dotted lines (Fig. 1) it will bereadily understood that pulley u' will be forced into contact with the belt s thereby tightening the latter, and causing the same to impart motion from the pulley e to the pulley p and its spindle p which, when set in revolution will seek to wind upon itself the several strips the ends of which have been previously suitably secured thereto. Said spindle p then serves to draw forward the several strips and cause the web of paper to unwind from the large roll. As soon as pressure is removed from foot-lever it said lever at once drops by gravity to the position shown in Fig. 1, in

full lines, the belt then again becoming slack and, as a consequence, stopping the re-windin operation of the machine.

in order that the several strips may be tightly wound upon spindle p We have pro vided a bar "0 rounded and inclined upon its under surface to permit of the gaper passingreadily over it, and supported vertically by arms 0 secured to a rocl' shat't w sup ported in frames a and 1). One edge of bar 1: engages the spindle p, or the rolls of paper thereon, at or about the level of the center of said spindle and to cause said bar to bear wLh considerable force against such spindle or rolls we have rigidly secured to the l'(l .'l-Hll{tfi; to, one or more arms w, extending approximately at right angles to arms v and heal-in on their free ends weir-ht ".5." [iv su nortin thc bar 0 transversely of the machine in th manner, the supporting arms 1) do not interfere with the strips of paper and the edge will press equally against the rolls of the rewound paper whether they are wide or narrow without any change or alteration.

l/Vhen it is desired to use a machine of our i proved form a roll of paper is first placed in the bearings c and the end of the web is paiised between the slitting knives 7t which cut and separate said roll into a multiple of narrow strips each of which is then. passed under the bar 1* and finally secured to the spindle p. When the machine is set in operation said strips are drawn forward and wound upon spindle 10, the bar '2; being meanwhile held forcibly against the circumferential faces of the several rolls creating a degree of tension sufficient to insure the compact rewindiug of said strips. The several strips are drawn tightly under the bar 22 and are thus prevented from riding upon each other and thus overlapping as they are rewound.

Having thus described our invention, we claim i 1. In a slitting and rewinding machine, the combination, with a frame provided with a slitting mechanism, of a rewinding spindle and means for optionally revolving it, said spindle being adapted to have more than one roll of material wound upon it, a bar located transversely of the machine intermediate the slitting mechanism and the spindle and movable toward and from the spindle substantially in a line therewith, one end of which is rounded and inclined upon its under surface and means for causing saidedge of the bar to bear against the rolls of material upon the spindle, substantially as set forth.

2. In a slitting and rewinding machine, the combination, with a frame provided with a slitting mechanism, of a rewinding spindle,

frictional actuating mechanism for optionally revolving the spindle, a rock-shaft journaled in the frame intermediate the slitting mechanism and the spindle, an arm rigidly secured to the rock-shaft adjacent each side the frame, a bar secured to said arms with its edge adapted to bear against the roll of material upon the spindle, and one of the arms being pro vided with an arm extending approximately at right angles thereto, and having a' Weight upon its outer cuthsubstantially as set forth.
